Well, I've taken a lot of heat for my suggestion. That's really how it should be when someone publishes a suggestion that's outside the norms of established safety practice. Reality is that I don't have an FES glider and if I had one I'd likely treat it quite conservatively for a long time. Getting bolder with its use would only happen if my own accumulation of experience as well as the experience of others had taught me that it was safe to do so.

Consider, though, that terrain isn't black and white, landable and unlandable; Landability is a matter of degree. Certain boulder strewn terrain would probably kill you whereas a rough pasture might take out your gear at worst. A road landing option or a narrow airstrip option might work but might send you on a ground loop. So along the spectrum of 'unlandable terrain' there would almost certainly exist a range of possibilities for the late use of FES. The reasonableness of that option is related to the strength of one's expectation that the motor will start in relation to the likely consequences if it doesn't. Luka's quote from Kawa reflects that notion.
